Backhaul Architecture and Implementation Training

Introduction:

Backhaul Architecture and Implementation Training Course by Example

Every new wireless device with any form of IP data, be it “traditional” browser data, texting, Voice over IP, video or other variations – which is virtually every wireless device today – must cross the “bridge” from the point where the wireless signal hits the cellular tower or wireless access point to the cloud. This Backhaul Architecture and Implementation Training course will provide a comprehensive look at how wireless signals cross the bridge from the cellular tower, leaving the wireless access point for another class. The approach to mobile backhaul for the cellular environment is vastly different than for the wireless access points because the bridge typically uses variations on traditional telco facilities, though this course will also discuss other architectures and options.

Customize It:

● If you are familiar with some aspects of this course, we can omit or shorten their discussion.
● We can adjust the emphasis placed on the various topics or build the course around the mix of technologies of interest to you (including technologies other than those included in this outline).
● If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the course in manner understandable to lay audiences.
